Abstract (en)
[origin: WO2021151712A1] Control system (19, 29, 33, 58) for frequency control of a laser module (20, 21), comprising at least one laser module (20, 21) for generating laser radiation, at least one control device (1) coupled or couplable to the laser module (20, 21), and at least one optical resonator (16, 23, 34) coupled or couplable to the control device (1), wherein the control device (1) comprises a semiconductor substrate (2), a first Pound- Drever-Hall system (3, 4, 22) embodied on the semiconductor substrate (2) and at least one second Pound-Drever-Hall system (3, 4, 22) embodied on the semiconductor substrate (2), wherein the laser module (20, 21) is coupled to the first Pound-Drever- Hall system (3, 4, 22) of the control device (1) and is couplable to the at least second Pound-Drever-Hall system (3, 4, 22) of the control device (1), and wherein the first Pound-Drever-Hall system (3, 4, 22) is coupled to the optical resonator (16, 23, 34) and wherein the second Pound-Drever-Hall system (3, 4, 22) is couplable to the optical resonator (16, 23, 34).
